Whenever you do get_posts or WP_Query or anything like that, it’s important to remember that the code is actually getting all of the Posts at once, and loading them from the database into memory. If you run out of memory, then your process will simply die with an error. Attempting to get very large numbers … Read more
Check out wp_cron and the cron_schedules filter. There are lots of good tutorials out there like this one from WPTuts or this one from Viper007Bond.
As described in wp_schedule_event first parameter is $timestamp – the first time that you want the event to occur. So just add interval to $timestamp. I think it should be like wp_schedule_event( time() + $delay, ‘interval1’, ‘my_cron_hook’ ); And set $delay as miliseconds before hook starts.
Or, you could use WP-CLI which was developed for scenarios like these. After a short installation like this $ curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar $ chmod +x wp-cli.phar $ sudo mv wp-cli.phar /usr/local/bin/wp You can run your scheduled tasks like so $ wp cron event run –due-now –path=/var/www/mywebsite.com/ or via crontab (every 5mins) */5 * * * … Read more
Yep, this does seem like a cron issue. Core Control plugin is good to diagnose cron tasks (among other things). I am still unsure what is the reason of you getting overrun with feed transients. However I had written some code that might help with automatic cleanup.
wp_cron is used to schedule tasks such as deleting old posts from trash, deleting old spam comments, and checking for plugin/theme updates.
The first step is setting up the cron job. The second part requires querying the database for a specific post type where the entry is older than 1 week. We can do this with get_posts() and specifying the category argument and the date_query argument. //* If the scheduled event got removed from the cron schedule, … Read more
Although I do not understand the motivation for truncating posts, I think this exercise is valuable for you to understand how to use cron + WordPress. Create a function to truncate posts This can be used for both methods below WP-cron or UNIX cron. function foobar_truncate_posts(){ global $wpdb; # Set your threshold of max posts … Read more
An idea I came up with was using the new WP Heartbeat API as opposed to using cron. Have your plugin fire off a call to your logging system every hour. Pippin’s tutorial contains the majority of the code you’ll need to get started.
Try this instead: $gloabl $myxclass; $myxclass = new Xwidget(); add_action( ‘xxx_followers’, array(&$myxclass, “cron_addB” ) ); or add_action(‘xxx_followers’, “init_xclass_and_cron”); function init_xclass_and_cron() { $myxclass = new Xwidget(); $myxclass->cron_addB(); }
